Description

Technical Field

[0001] This utility model relates to the technical field of feed additive packaging machines, specifically to a multi-outlet switching feed additive packaging machine. Background Technology

[0002] Feed additive packaging machines are primarily used for the automated packaging of feed additives to improve packaging efficiency and reduce manual operation. They mainly consist of one or more packaging units, each equipped with an independent metering and sealing device. The metering device precisely controls the amount of feed additive added, ensuring that the weight or volume of each package meets preset standards. The sealing device is responsible for sealing the packaging bag after packaging to prevent the feed additive from becoming damp, deteriorating, or leaking during transportation or storage.

[0003] In small-batch production, it is necessary to simultaneously package bags of different specifications to meet diverse production needs. However, the single-outlet fixed packaging machines on the market have a simple structure but low efficiency, cannot perform multiple tasks in parallel, and have complex weighing operations for different specifications. Therefore, we propose a multi-outlet switching feed additive packaging machine. Utility Model Content

[0004] The purpose of this utility model is to solve the problems of single-outlet fixed packaging machines on the market, which have simple structure but low efficiency, cannot perform multiple tasks in parallel, and have complicated weighing operations for different specifications. This utility model provides a multi-outlet switching feed additive packaging machine.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0006] A multi-outlet switching feed additive packaging machine includes a fixed base, a heat-sealing seat fixedly connected to the upper center of the fixed base, a central column fixedly connected to the upper center of the heat-sealing seat, and a storage hopper fixedly connected to the upper end of the central column. A rotary weighing platform is rotatably mounted on the upper outer ring of the heat-sealing seat. Multiple weighing hoppers are arrayed on the upper side of the rotary weighing platform's turntable, and a discharging mechanism is correspondingly provided on the side wall of the central column. Multiple metering discharge valves are arrayed and fixedly connected to the bottom of the storage hopper. Multiple receiving hoppers are arrayed and fixedly connected to the side wall of the heat-sealing seat, and back-sealing packaging devices are respectively provided in the middle of the side wall of the heat-sealing seat corresponding to the multiple receiving hoppers. The number of receiving hoppers and metering discharge valves is twice the number of weighing hoppers.

[0007] Furthermore, a tilting seat is fixedly connected to the upper end of the rotary weighing platform corresponding to the position of the weighing hopper, and a fixed tilting arm is fixedly connected to the bottom of the weighing hopper. The bottom of the fixed tilting arm is hinged to the tilting seat, and a half-circle gear is provided at the lower end of the fixed tilting arm. A drive rack is slidably inserted into the upper end of the tilting seat. An adsorption iron end plate is fixedly connected to the drive rack on the side facing the central column, and an electromagnet is fixedly installed on the side wall of the central column corresponding to the position of the adsorption iron end plate. A return spring is provided between the adsorption iron end plate and the central column.

[0008] Furthermore, a limiting slide rod is fixedly connected to the outer wall of the central column corresponding to the center of the adsorption iron end plate, and the front end of the limiting slide rod is movably inserted into the center of the adsorption iron end plate.

[0009] Furthermore, the metering unloading valve includes a valve seat, a valve core, and a drive motor. The valve core has a cylindrical structure, and a matching cylindrical valve cavity is opened at the center of the valve seat corresponding to the valve core. The valve seat has connecting holes at both the top and bottom, and multiple quantitative transfer grooves are arrayed on the side wall of the valve core. The drive motor is located on the outside of the valve seat, and the output shaft of the drive motor passes through the valve seat and is fixedly connected to the valve core.

[0010] Furthermore, each pair of adjacent metering discharge valves forms a pair, and the volume ratio of the quantitative transfer troughs on the two metering discharge valves is 100 to 1.

[0011] Furthermore, the center of the rotary weighing platform is rotatably mounted on the outer wall of the central column via a bearing, and a plane bearing is provided between the bottom of the rotary weighing platform and the upper end of the heat sealing seat. A driven gear is fixedly connected to the bottom surface of the rotary weighing platform corresponding to the outer side of the central shaft hole, and a servo rotary motor is fixedly connected to the upper end of the heat sealing seat at an eccentric position. The output shaft of the servo rotary motor is fixedly connected to a driving gear, and the driving gear meshes with the driven gear on the bottom surface of the rotary weighing platform for transmission.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This utility model allows feed additives to enter the corresponding weighing hopper from the bottom of the storage hopper through an open metering discharge valve. Once the preset weight is reached, the metering discharge valve closes. Subsequently, the rotary weighing platform rotates, moving the weighing hopper containing the feed additives to the receiving hopper of the corresponding packaging size. Then, the pouring mechanism activates, pouring the feed additives into the corresponding receiving hopper. The additives then enter the back-sealing packaging unit through the receiving hopper. The back-sealing unit activates, heat-sealing the packaging bag in the receiving hopper, completing the packaging of one bag of feed additives. Next, the rotary weighing platform continues to rotate, and the empty weighing hopper moves to the bottom of the storage hopper, repeating the above process for continuous packaging. The multiple outlets allow this packaging machine to handle the packaging of various feed additives simultaneously, improving work efficiency.

[0014] 2. This invention utilizes an electromagnet that is intermittently energized to generate magnetism, thus creating an intermittent attraction force on the iron end plate. When the electromagnet is energized, the iron end plate is attracted and moves towards the central column, causing the drive rack to slide on the tilting seat. The drive rack meshes with the half-circle gear at the lower end of the fixed tilting arm, causing the fixed tilting arm to tilt the weighing hopper and empty the feed additives inside. When the electromagnet is de-energized, the iron end plate is reset by the return spring, causing the weighing hopper to return to its original position, ready for the next loading. This design achieves automatic tilting and emptying of the weighing hopper without manual operation, improving automation and work efficiency.

[0015] 3. This utility model uses a drive motor to rotate the valve core within the valve seat. When the quantitative transfer trough aligns with the upper and lower connecting holes of the valve seat, feed additives enter the weighing hopper from the storage bin through the connecting holes and the quantitative transfer trough, achieving precise measurement. Once the preset weight is reached, the drive motor continues to rotate, causing the quantitative transfer trough to shift away from the connecting holes, closing the metering channel, and completing one metering and unloading process. This metering unloading valve is ingeniously designed and has a simple structure, enabling rapid and accurate metering of feed additives, thus improving the metering accuracy and working efficiency of the packaging machine.

[0022] Please see Figures 1-4This utility model provides a multi-outlet switching feed additive packaging machine, including a fixed base 1. A heat sealing seat 2 is fixedly connected to the upper center of the fixed base 1. A central column 10 is fixedly connected to the upper center of the heat sealing seat 2, and a storage tank 15 is fixedly connected to the upper end of the central column 10. A rotary weighing platform 3 is rotatably installed on the upper outer ring of the heat sealing seat 2. Multiple weighing hoppers 7 are arrayed on the upper side of the turntable of the rotary weighing platform 3. A material pouring mechanism is provided on the side wall of the central column 10 corresponding to 17. Multiple metering discharge valves 13 are arrayed and fixedly connected to the bottom of the storage tank 15. Multiple receiving hoppers 4 are arrayed and fixedly connected to the side wall of the heat sealing seat 2. A back sealing packager 5 is provided on the middle of the side wall of the heat sealing seat 2 corresponding to the multiple receiving hoppers 4. The number of receiving hoppers 4 and metering discharge valves 13 is twice the number of weighing hoppers 7.

[0023] The working principle and usage process of this utility model are as follows: During use, feed additives enter the corresponding weighing hopper 7 from the bottom of the storage bin 15 through the open metering discharge valve 13. Once the preset weight is reached, the metering discharge valve 13 closes. Subsequently, the rotary weighing platform 3 begins to rotate, moving the weighing hopper 7 containing the feed additives to the receiving hopper 4 of the corresponding packaging size. Then, the pouring mechanism is activated, pouring the feed additives into the corresponding receiving hopper 4. The additives then enter the back-sealing packaging unit 5 through the receiving hopper 4 for packaging. At this time, the back-sealing packaging unit 5 is activated, heat-sealing the packaging bag in the receiving hopper 4 to complete the packaging of one bag of feed additives. Next, the rotary weighing platform 3 continues to rotate, and the empty weighing hopper 7 moves below the storage bin 15, repeating the above process to achieve continuous packaging. The multiple outlets allow this packaging machine to handle the packaging of various feed additives simultaneously, improving work efficiency.

[0024] The back-sealing packaging machine 5 adopts the same structural principle as the DXDF60-II and XY series back-sealing automatic powder packaging machines of companies such as Xi'an Xinghuo and Anhui Xinyuan, and uses back-sealing bag making technology for packaging.

[0025] In this embodiment, preferably, a tilting seat 6 is fixedly connected to the upper end of the rotary weighing platform 3 corresponding to the position of the weighing hopper 7, and a fixed tilting arm 8 is fixedly connected to the bottom of the weighing hopper 7. The bottom of the fixed tilting arm 8 is hinged to the tilting seat 6, and a half-circle gear is provided at the lower end of the fixed tilting arm 8. A drive rack 9 is slidably inserted into the upper end of the tilting seat 6. An adsorption iron end plate 11 is fixedly connected to the side of the drive rack 9 facing the central column 10, and an electromagnet is fixedly installed on the side wall of the central column 10 corresponding to the position of the adsorption iron end plate 11. The adsorption iron end plate 11 and the central column 10 are connected... A return spring 12 is installed in the weighing hopper. An electromagnet is intermittently energized to generate magnetism, thus creating an intermittent attraction force on the adsorption iron end plate 11. When the electromagnet is energized, the adsorption iron end plate 11 is attracted and moves towards the central column 10, causing the drive rack 9 to slide on the tilting seat 6. The drive rack 9 meshes with the half-circle gear at the lower end of the fixed tilting arm 8, causing the fixed tilting arm 8 to tilt the weighing hopper 7, emptying the feed additives inside. When the electromagnet is de-energized, the adsorption iron end plate 11 is reset by the return spring 12, causing the weighing hopper 7 to return to its original position, ready for the next loading. This design achieves automatic tilting and emptying of the weighing hopper 7 without manual operation, improving automation and work efficiency.

[0026] In this embodiment, preferably, a limiting slide rod is fixedly connected to the outer wall of the central column 10 corresponding to the center of the adsorption iron end plate 11, and the front end of the limiting slide rod is movably inserted into the center of the adsorption iron end plate 11. The limiting slide rod guides and limits the movement of the adsorption iron end plate 11, ensuring its stability during movement and preventing offset or wobbling. This ensures stable meshing transmission between the drive rack 9 and the half-circle gear, improving the reliability and service life of the device. The design of this limiting slide rod is simple and practical, effectively solving the positioning problem of the adsorption iron end plate 11 during movement.

[0027] In this embodiment, preferably, the metering unloading valve 13 includes a valve seat, a valve core, and a drive motor. The valve core has a cylindrical structure, and a matching cylindrical valve cavity is opened at the center of the valve seat corresponding to the valve core. The valve seat has connecting holes at both the top and bottom, and the sidewall of the valve core has an array of multiple quantitative transfer grooves 14. The drive motor is located outside the valve seat, and its output shaft passes through the valve seat and is fixedly connected to the valve core. The drive motor drives the valve core to rotate within the valve seat. When the quantitative transfer grooves 14 align with the connecting holes at the top and bottom of the valve seat, the feed additive enters the weighing hopper 7 from the storage tank 15 through the connecting holes and the quantitative transfer grooves 14, achieving precise metering. When the preset weight is reached, the drive motor continues to rotate, causing the quantitative transfer grooves 14 to offset the connecting holes, closing the metering channel, and completing one metering unloading process. This metering unloading valve 13 is ingeniously designed and has a simple structure, enabling rapid and accurate metering of feed additives, thus improving the metering accuracy and working efficiency of the packaging machine.

[0028] In this embodiment, preferably, every two adjacent metering unloading valves 13 form a pair, and the volume ratio of the quantitative transfer grooves 14 on the two metering unloading valves 13 is 100 to 1; the volume ratio of the quantitative transfer grooves 14 on every two adjacent metering unloading valves 13 is designed to be 100 to 1, so that different metering unloading valves 13 can be selected for combination according to the needs of different packaging specifications, which is flexible, convenient and has a wide range of applications.

[0029] In this embodiment, preferably, the center of the rotary weighing platform 3 is rotatably mounted on the outer wall of the central column 10 via a bearing, and a plane bearing is provided between the bottom of the rotary weighing platform 3 and the upper end of the heat sealing seat 2. A driven gear is fixedly connected to the outer side of the bottom surface of the rotary weighing platform 3 corresponding to the central shaft hole, and a servo rotary motor is fixedly connected to the upper end of the heat sealing seat 2 at an eccentric position. The output shaft of the servo rotary motor is fixedly connected to a driving gear, and the driving gear meshes with the driven gear on the bottom surface of the rotary weighing platform 3 for transmission. The servo rotary motor drives the driving gear to rotate, and the driving gear meshes with the driven gear on the bottom surface of the rotary weighing platform 3 for transmission, causing the rotary weighing platform 3 to rotate around the central column 10. This design makes the rotation of the rotary weighing platform 3 stable and reliable, and the precise control of the servo rotary motor can realize the precise positioning and rotation speed adjustment of the rotary weighing platform 3, thereby meeting different packaging requirements. In addition, the plane bearing reduces the frictional resistance of the rotary weighing platform 3 during rotation, improving the smoothness and efficiency of rotation.
